eXfat

So you got a nice 64GB USB stick, and can’t format it NTFS but want to transfer huge files on it. You probably formatted it with eXfat (Windows Vista, 7, 8, Mac)

But the ISO you downloaded is on your XP machine, you can compress it and span the 4GB limit set by FAT(32) OR, you can just install eXfat support on Windows XP using the download provided by Microsoft themselves:
